as compared to the main GWAS results. The full set of P-values that emerged from the PLINK association analysis were loaded and visualized in Haploview ver. 4.1 [Barrett et al., 2005] and WGAViewer ver. 1.25. These two programs were used to compute LD patterns and haplotype maps, generate quantile-quantile (Q-Q) plots, and annotate top-ranking SNPs with the latest available genomic databases.
